[jbossts-issues] [JBoss JIRA] (JBTM-2440) Byteman tests fail when running with the IBM JVM

[Michael Musgrove (JIRA)]

    [ https://issues.jboss.org/browse/JBTM-2440?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13086334#comment-13086334 ] 

Michael Musgrove commented on JBTM-2440:
----------------------------------------

The [IBM manual | http://download.boulder.ibm.com/ibmdl/pub/software/dw/jdk/docs/java8/lnx/en/sdkandruntimeguide.lnx.80_8.0.pdf] says

bq. The Attach API can be enabled by setting the com.ibm.tools.attach.enable system property to the value yes;

I tried this but tests marked up with the @BMUnitRunner annotation still fail with the error JVMTI_ERROR_NOT_AVAILABLE

I tried enabling it in the pom via:
* systemPropertyVariables;
* systemProperties; and
* <argLine>-Dcom.ibm.tools.attach.enable=yes</argLine> 

none of which work.

I am going to work around the issue using an ibm jdk profile that disables byteman tests.

> Byteman instrumentation does not work with the IBM J9 JVM:- it fails with errors like the following:
> {code}
> *** java.lang.instrument ASSERTION FAILED ***: "jvmtierror == JVMTI_ERROR_NOT_AVAILABLE" at JPLISAgent.c line: 1009
> Exception in thread "Attachment 59984" Agent failed to start!
> JVMJ9TI064E Agent initialization function Agent_OnAttach failed for library instrument, return code 102
> {code}
> I will implement a workaround by disabling byteman when testing with this JVM.
